System and Method for Pitch Detection and Analysis

ABSTRACT

Systems and methods are shown for pitch detection involving a first linear array with multiple detection devices for detecting an object mounted on a base for positioning near the front of home plate, adjacent the front edge of the home plate. Some examples include an indicator on each detector to indicate detection. In some examples, the detectors communicate detection to an analysis system. In some examples, the analysis system determines and displays a pitch result from the position of the detect object. In other examples, a second is positioned at a known distance from the plate and communicates a detection position to the analysis system, which determines pitch speed and result from the two positions. In another example, three arrays are used to determine a curved pitch path. Another example has an array positioned near the back of the plate for determining pitch result, path and speed.

BACKGROUND

Baseball and softball are games that require a pitcher to throw a ball within a strike zone at home plate in order to earn a strike against the batter and any pitches outside of the strike zone represent balls against the pitcher. The strike zone is defined as the volume of space over home plate between the batter's knees and mid-point of their torso. FIG. 1 is an aerial view schematic diagram illustrating an example of a home plate 10. An umpire judges or calls whether a pitch is a ball or strike, which requires training and practice, but may still result in errors or bad calls. Video replay is often used to analyze the call on a pitch, but this analysis occurs after the fact of the pitch itself.

SUMMARY

According to one aspect of the present invention, an example of a pitch detection system for use in detecting strikes is shown, where the system includes a first linear array with a base member having a linear length that is at least the length of a front edge of a home plate, where the base member is to be positioned adjacent the front edge of the home plate. Multiple detection devices are attached along the linear length of the base member and each has an emitter for producing a detection beam and a detector for receiving reflected energy of the detection beam to detect an object. In some examples, each detection device includes an indicator for indicating that the detector has detected an object.

In an example of a further refinement, the detection devices of the first array also have a communication interface to communicate that the detector has detected an object and a position of the object and the system has an analysis system configured to communicate with the detection devices, where the analysis system determines a pitch result from the position of the detected object and the pitch result is displayed.

In still another example of a refinement, the system has a second array of detection devices configured to be positioned at a known distance from home plate and detect an object and communicate the detection position and detection time to the analysis system, the first array of detection devices is further configured to communicate detection time to the analysis system, and the analysis system determines a pitch speed from the detection time at the first array, the detection time at the second array, and the known distance from home plate of the second array and may also display the pitch speed.

In yet another refinement, the pitch detection system has a second array of detection devices configured to be positioned at a known distance from home plate and detect an object and communicate the detection position to the analysis system, which determines a pitch path from the detection position at the first array and the detection position at the second array and determines an intersection of the pitch path with a strike zone volume of the home plate in order to obtain a pitch result, where the pitch result or pitch path or both may be displayed.

Still another refinement involves a third array of detection devices configured to be positioned at another known distance from home plate and detect an object and communicate the detection position to the analysis system, which determines the pitch path from the detection positions at the first, second and third arrays to obtain a two dimensional curved pitch path and determines the intersection of the pitch path with the strike zone volume of the home plate utilizing the two dimensional curved pitch path.

Further still, in another refinement of the pitch detection system, the detection devices of the first and second arrays are further configured to detect and communicate a detection height and the system includes a third array of detection devices configured to detect an object and communicate detection position and detection height to the analysis system and the third array is configured to be positioned at another known distance from home plate. The analysis system determines the pitch path from the detection positions and heights at the first, second and third arrays to obtain a three dimensional curved pitch path, and determines the intersection of the pitch path with the strike zone volume of the home plate utilizing the three dimensional pitch path.

In another example of a refinement of the pitch detection system, the detection devices of the first and second arrays are further configured to detect and communicate a detection height and a detection vertical speed. The analysis system determines the pitch path from the detection positions, heights and vertical speeds at the first and second arrays to obtain a three dimensional curved pitch path, and determines the intersection of the pitch path with the strike zone volume of the home plate utilizing the three dimensional pitch path.

In an additional example of a refinement of the pitch detection system, the detection devices of the first array are further configured to detect and communicate detection height and detection vertical speed. The analysis system determines a sinking speed of the pitch from the detection vertical speed, determines a pitch vector from the sinking speed, detected position and detect height, and determines the intersection of the pitch path with the strike zone volume of the home plate utilizing the pitch vector.

In still another example of a refinement of the pitch detection system, one or more of the arrays are embedded in a home plate.

DETAILED DESCRIPTION

The subject matter of embodiments of the present invention is described here with specificity to meet statutory requirements, but this description is not necessarily intended to limit the scope of the claims. The claimed subject matter may be embodied in other ways, may include different elements or steps, and may be used in conjunction with other existing or future technologies. This description should not be interpreted as implying any particular order or arrangement among or between various steps or elements except when the order of individual steps or arrangement of elements is explicitly described.

FIG. 2 is a schematic diagram illustrating an example of a pitch detection apparatus 100 having a detector array 110 in accordance with at least one embodiment of the invention. Detector array 110 is positioned substantially adjacent a leading edge of home plate 10. As a result, a ball pitched to home plate 10 will cross detector array 110 immediately before it intersects the leading edge of home plate 10. FIG. 3 is a schematic diagram illustrating one example of the pitch detection array of FIG. 2, where a series of detectors 122A-G are coupled together by a base member 120. Each of the detectors 122A-G projects a detection beam 124, such as detection beam 124G corresponding to detector 122G. The detectors 122A-G are positioned on base member 120 to cover the strike zone across the front of home plate 10. In some examples, additional detectors outside the strike zone, e.g. ball zones, may also be provided.

Detectors may utilize a variety of different technologies, such as laser, photo-optics, infrared, SONAR or radar, that are capable of detecting the presence of a projectile, such as ball 140. Generally, the detection beam provided must be sufficiently focused to differentiate the position of one detector from another as the ball passes over detector array 110. One of ordinary skill in the art will appreciate that many technologies may be adapted for use in the detection array. In the example shown, ball 140 passes over array 110 and intersects detection beam 124G resulting in detector 122G detecting the ball.

FIG. 4 is a functional block diagram illustrating one example of the function of the detection devices 122A-G of the array 110 of FIG. 3. In this example, emitter 132 generates detection beam 124, e.g. a laser device producing a laser beam. Detection beam 124 reflects off ball 140 producing reflected beam 125, which is detected by detector 134, e.g. an optical device configured to detect the frequency of the laser light produced by emitter 132. In this example, detector 134 is coupled to an indicator 136, which may be a light that is activated to indicate detection. In some embodiments, detector 134 includes a network interface to permit communication with other devices so that it can transmit information regarding the detection event. Note that detector devices may be utilized that can measure the height of the ball as it passes over the detector and/or the speed of the ball with respect to the detector, e.g. vertical speed of the ball or how fast the ball is sinking or rising as it passes across the detector, such as through measuring a Doppler shift of the reflected beam 125 with respect to detection beam 124.

FIG. 5 is a functional block diagram illustrating an example of a multiple array pitch detection system 200 in accordance with at least one embodiment of the invention. In this example, three detector arrays 110A, 110B and 110C are positioned at known distances D1 and D2 from one another and array 110A is positioned on the leading edge of home plate 10. While three arrays are shown in the example, either more or fewer arrays may be utilized in other embodiments. When ball 140 is pitched toward home plate 10, its path 212, in this example, takes it across each of the detector arrays, which detect the position of the ball.

Detector arrays 110A, 110B and 110C, in this example, are connected to analysis system 210 through a network, which may be wired or wireless. Analysis system may take the form, for example, of a personal computer or other computing device that communicates with detector arrays 110A, 110B and 110C to collect data regarding the pitch path 212.

FIG. 6 is a control flow diagram illustrating an example of a simple process 250 for pitch detection in accordance with at least one embodiment of the invention, such as an embodiment with a single detector array, e.g. array 110A in FIG. 5. At 252, the detection devices 122 of array 110A detect the position of the ball 140 as it passes across array 110A by, for example, being detected by one of the detection devices 122. At 254, a strike or ball may be determined from the position detected based on which detector device 122A-G detected the ball. At 256, the strike or ball result is displayed.

In one embodiment, a light in one of the detector devices 122A-G is activated or changed to indicate the detection position. If detector devices in array 110A are provided that cover the area outside the strike zone, then the indicator lights for these devices may have a different indicator color than the detector devices within the strike zone. No analysis system is utilized in this embodiment.

In another embodiment, analysis system 210 is in communication with the detector devices 122A-G of array 110A, collects the position data from the detector devices, and displays the ball or strike result on, for example, a display monitor or an audible signal.

Note that the strike zone coverage provided by a single array 110A is one dimensional and provides a basic indication of whether the pitch is a ball or strike. In certain scenarios, it may provide some erroneous results. For example, a pitch that crosses home plate 10 from an oblique side angle may not be detected or may be detected as a ball. Also, no other information regarding the pitch is provided.

FIG. 7 is a control flow diagram illustrating another example of a process 260 for pitch detection and analysis involving two detection arrays in accordance with at least one embodiment of the invention. In this example, arrays 110A and 110B are utilized and are at a known distance D1 from one another. The analysis system 210 in this example is designed to collect the time of detection in addition to the position of detection. For instance, the detector devices may be designed to create a timestamp when a pitch is detected. Or the detection devices send a message reporting a position detection and analysis system 210 derives the time of detection from the messaging.

At 262, in one example, a detection device in array 110A detects the ball and reports the position and timestamp to analysis system 210. At 264, a detection device in array 110B detects the ball and reports the position and timestamp to analysis system 210. At step 274, analysis system 210 determines the speed of the pitch from the position and timestamp data along with the displacement distance D1 between arrays 110A and 110B. At step 274, analysis system 210 determines an angle of the pitch path from the positions detected at first array 110A and second array 110B. At 272, analysis system 210 determines from the pitch path angle whether the pitch path would intersect the strike zone volume above home plate 10. At 278, the strike/ball pitch result, the speed and the pitch path angle are displayed. Thus, this embodiment is able to provide additional information regarding the pitch, such as a basic two dimensional determination of pitch result, pitch speed and pitch angle.

Note, however, that the example pitch path 212 in FIG. 5 is slightly curved, as often occurs in some types of pitches, e.g. a slider. FIG. 8 is a control flow diagram illustrating another example of a process 300 for pitch detection and analysis involving three arrays 110A, 110B and 110C, where the detectors are configured to capture the time and position of detection, in accordance with at least one embodiment of the invention. At 302, 304 and 306, each of the arrays 110A, 110B and 110C, respectively, reports the time and position of pitch detection. At 310, the three data points provided from the arrays are used to calculate the pitch path curve. At step 314, the pitch path curve result is used to determine whether the pitch path 212 intersected the strike volume above home plate 10 to obtain the pitch result. At 316, the pitch result and pitch path curve results are displayed as well as the pitch speed determined at 312.

FIG. 9 is a control flow diagram illustrating another example of a process 350 for pitch detection and analysis involving three arrays, where the detectors are configured to capture the height of the ball at time of detection, in accordance with at least one embodiment of the invention, such that three dimensional information regarding the pitch may be derived. In this example, the detector devices 122A-G provided in each of the arrays 110A-C are capable of detecting and reporting the height of the ball relative to the detector device along with position and time of detection. At 352, 354 and 356, arrays 110A-C, respectively, report the position, time and height of detection for the ball 140 as it passes across the arrays on its pitch path 212. At 360, a three dimensional pitch path curve is calculated from the position and height of the ball at the three arrays 110A-C. At 362, the three dimensional pitch path curve is used to determine whether the pitch path 212 intersected the strike zone volume. Note the use of height data allows the strike zone volume to be limited by height, e.g. above a certain height and below another height, giving a more accurate and complete pitch result. At 364, the height data may be used to determine whether the pitch path is sinking or rising, which may be useful for analyzing certain pitches, such as curve balls. At 366, the pitch result, three dimensional pitch path curve and sinking or rising results are displayed. This example may also be adapted to determine and display pitch speed in a manner similar to that discussed above.

FIG. 10 is a control flow diagram illustrating another example of a process 370 for pitch detection and analysis involving an array with detectors configured to detect vertical speed of the ball at time of detection in accordance with at least one embodiment of the invention. In this example, a single array 110A is used having detection devices capable of detecting position, height, vertical speed and time of detection. Vertical speed, in this example, means the speed of the ball relative to the detector. For example, as mentioned above, a Doppler shift of the reflected beam relative to the detection beam may be utilized to determine the speed of the ball as it sinks or rises relative to the detector. At 372, this data is detected when the ball passes over array 110A. At 374, the sinking or rising speed of the ball is determined from this information. At 376, the sinking or rising speed results are used along with position and height to determine a three dimensional pitch path angle or vector. At 378, the three dimensional pitch path angle or vector is used to determine intersection of the ball with the strike volume for the pitch result. At 379, the pitch result, sinking or rising speed, and the three dimensional pitch path vector are displayed.

FIG. 11 is a control flow diagram illustrating another example of a process 380 for pitch detection and analysis involving two arrays 110A and 110B, where the detectors 122A-G are configured to capture height, vertical speed and the time of detection, in accordance with at least one embodiment of the invention. At 382 and 384, arrays 110A and 110B capture this data. At 390, analysis system 210 calculates the pitch path vector at each array and then, from the two vectors, calculates a three dimensional pitch path curve, e.g. from a change in vector direction, a curve can be inferred. The pitch path curve may be utilized to determine intersection with the strike zone volume, as described above. At 392, the speed of the pitch is determined from the time difference between the detection events at arrays 110A and 110B along with the displacement distance D1 between the arrays. At 394, sinking or rising speed is determined from the vertical speed data. At 396, this data is displayed.

FIG. 12 is a schematic diagram illustrating another example of an arrangement of pitch detection arrays 400 in accordance with at least one embodiment of the invention. In this example, a first detector array 110A is arranged along a leading edge of home plate 10 and second and third arrays 110D and 110E are arranged along the angled rear edges of home plate 10 so that the arrays are able to detect a ball path across home plate 10 when it encounters the leading edge and one of the rear edges.

FIG. 13 is a schematic diagram illustrating an example of a home plate 460 with embedded pitch detection arrays 470A, 470B and 470C in accordance with another embodiment of the invention. In the example of FIG. 14, the detector devices for the arrays are embedded in a home plate body or material along the leading and rear edges of home plate 460.

The processes described above, such as Process 260 of FIG. 7 may be implemented to process path data collected by arrays 110D and 110E or 470A, 470B and 470E in order to analyze pitches, such as determining pitch result, pitch angle or speed. Note that additional detectors may be arranged along the side edges of home plate 10 in FIG. 13 or embedded in the side edges of home plate 460 and the processes implemented to utilize this data as well in analyzing pitches.
